So there's a few threads here that offer pieces of information on how to install a ROM, CWM, etc ... but almost none of them really explain to me what exactly an nvflash is, what 1.2 means, what the 250m or 350m (or whatever they are) are for ... or how to detect whether or not I need those? Each of the rom threads just say "hey you need this," but I can't seem to find how to find out what I have, what I need, where to get it, etc. Can anyone offer some advice trying to flash this thing for a friend?
Thanks.

I am a semi-noob here, meaning I have some experience in flashing roms on samsung phones but things like nvflash on transformer prime confuse me. I can't seem to find a clear enough explanation on what it really is (does it save some important files that somehow allow you to bring back the tablet from a brick?), how it's applied or how it is normally used when it is needed.
I've been wanting to flash the official JB stock rom (all other roms have been disappointing so far) but everyone says nvflash is highly recommended, so until I learn what it's all about I'm not willing to go any further.
Can anyone point me to a simple enough guide?
On a separate note, can anyone tell me how I would go about flashing twrp again safely after flashing stock JB?

Go to Development Section of this Forum. There is a "Sticky" about NVFlash and Also Video on How to.
Thanks, I didn't know about the video - Cheers!
Sorry to jump in another thread, but I need further help. Unfortunately I can't understand the video so much. My scenario is: I have all the NVFlash backups, I am currently on AndroWook JellyBean 1.2 and want to revert back to stock ICS in order to get the FOTA. I didn't find a tutorial on how to revert back to the files I saved... Can anyone help?
Being newly interested in rooting and tweaking my devices (started with my S3) there are a lot of terms that are mentioned in customizing threads that I do not understand, and a lot of those threads don't have detailed instructions for someone that's new to tweaking. Is there one post somewhere on xda that lists terms, methods, etc for newcomers like me?
I don't trust any forum other than xda because I simply think its the best forum for tweaking, etc so I don't really trust links outside xda. I also know that the way some things need to be done is device specific.
I'm confused about how to "flash" something in "recovery' (such as removing the wifi notification thread), flashing a custom recovery, using Goomanager to flash, etc. Don't get me wrong; I can follow detailed instructions as long as they are there......but if they aren't, that leaves me and a great deal of newcomers in the dark.
Some of these things are done via the phone and some have to be done via PC....and many times there aren't detailed instructions so I'm unsure what I an supposed to do and don't want to brick a $700 device.
So....is this information contained in all separate posts throughout the forum? Or is there one thread per device that details it? Being as some of these things are device specific, I'm hesitant to even look in other device forums.
Thanks for reading, and any assistance is appreciated.

Well, this can be a complex arena to play in. For the S4, you'll want to download Odin v3.07 and a copy of the stock ROM just in case you break something.

ROM = read-only memory - this is the part of your phone's internal storage you're not really supposed to be able to play with (like /system, or the phone's radio for example)
The act of "flashing" is writing data to ROM
Recovery just means that you should always be able to boot your device into this mode to RECOVER from a software problem; IE: flashing a bad ROM (IE: one that doesn't work and you can't start your phone anymore).
I don't really know a whole lot more than that, I just poke around and pretend like I do =)

Thanks As I learn more, I think I'm going to make a post that contains everything I learn, so others have it all in one place.
Well, there's a LOT to learn...like I said; complex arena. So much so that there's no way to make a single post take you from newbie to knowledgeable newbie in one read.
Then there's Google;
"what is rom"
"what is flashing rom"
"what is recovery mode android"
Eliminates the need for said post
Plus, by the time you get it all written, it will have all changed ^_^
I need some help with this, and seeing that people have worked on the Infobar A01/02 I would assume there's people here who can tackle this. I have no idea how you would go about Rooting or Unlocking a SHARP device, let alone a Japanese one and I don't see the C01 listed anywhere.
I'd also like to know how I would go about installing a ROM alongside the default one on here.

Anyone at all? The least I'd need to know is how to boot into recovery mode. I found one site that talks about the power and volume buttons at startup but nothing happens. I've gotten into recovery with a G1 but that's about it. Do I have to like inject my own recovery bootloader or something?
Bumping, still no luck on finding a GingerBread 2.3.4 rooting option.
I'm trying to inject su and Superuser manually but I can't mount with the recovery menu, so I'm trying to install CWM but I need root to do that, but that gives me root to give myself root. l:L
I'm in a vicious cycle, pls send hepl im dyign
What's a universal root method for GingerBread 2.3.4?
Just found out you can't get a universal root for 2.3.4 and that you have to have a custom method. Ho how would you go about making a root method at all?
I also think that the phone has a locked bootloader which would explain why I can't access the recovery menu options. I feel a bit silly, I suppose that's a large reason why some of this stuff isn't working at all. If anyone knows some Infobar bootloader stuff just feel free to post.
I just found a thread about someone else trying to figure out all of the things I'm trying to figure out only it's not on an Infobar but another Sharp device on KDDI. I think they eventually found someone else had made a root, but I kinda didn't read the entire thread. Still wondering if anyone has already got a solution.
Much the same
I have a c01 here in the UK, still wearing factory stickers. A very poor buy, considering I can't make a call with it. I have looked high and low but can't get anywhere with it. Sharp/kddi/AU I have asked them all. No can do. Although I read a Canadian chap had his unlocked by them, they simply won't at any cost.
I can't even get a phone shop to look at it.
To be honest, I know about as much as my gran about mobiles. I'm a quick study, but would rather pay, if there was somebody to pay.
Any positive direction would be much appreciated. Best advice so far is to bin it and try to forget.
I have to start by telling you I am not only a Newbe I am a NO-Knowbee, a complete novice. I am an advanced computer user but smart phones make me fell stupid. So please bear that in mind when offering "how to" advice.
I bought this phone 3 weeks ago as Rooted. I think is was rooted but SuperSU will not start. I get a message that the SU Binary need to be updated. I have two choices. NORMAL which fails and the other is TWRP/CWM which does nothing either but suggests I manually reboot into recovery manually. I have no idea what to do.
Nice mess there ... maybe others have better opinion here but .. the question would be to fine out what version of android you have (aka like windows xp, 7, 8/8.1 etc) then from that point I would almost want to start over ..
Some people have differ opinions on this but my opinion is to start over and re-root the phone. Either they failed on the unlocking boot loader or something and just decided to sell it. (in windows terms they basically corrupted everything).
So the question comes down to is being able to put on custom roms? Depending circumstances you can unlock the boot loader and then install any custom rom (modified OS made for that specific phone, you cant just put anything it has to be made for this phone etc..)
Next question if you can live without going through that (different roms) and want to stick with stock (whats already on the phone) and just want root, then the my opinion would be to just redo everything then re-root it fresh.
Theres a program called Odin that you would use and you would need the stock file to which is currently on your phone and you would need to download it (the file is usually about over a GB in size) and you would need to do that. However telling you how to do that here while its simple this is something you need to read and learn about. Its just like finding tweaks and tips on windows. There's a EXCELLENT help section here and I HIGHLY recommend you read and read more and more. Its like potato chips you cant eat just one. Good luck.
Maybe the problem is that I don't know how to properly ask for what I want/need. First off, I am new, so let's pretend I know nothing about modding phones. Second, what I am trying to achieve is the following:
Marshmallow OS or newer (I have lollipop and I highly dislike it)
Complete removal of all AT&T software/bloatware from my M8
Ability to try out different ROMs (are those the same thing as operating systems?) like cyanogenmod.
Those are the highlights to my endgame.
I have found there are several steps to this, and it seems like each step has at least one prerequisite or sub-step and I get overwhelmed when reading up on how to achieve the above goals. Feels like I'm doing taxes for a poorly run business. Apparently I need TWRP on my phone. No clue why or what it does. In order to install it, I need to have root access or a previous version of TWRP already installed, or I need to install the SDK tools package, and from that, only install fastboot and adb. Then after that I need to already have some type of drivers on my PC for that to be useful. Like I said, it is overwhelming to someone who does not know all of the lingo. Especially when I know that if I mess up at certain intervals, I could very well turn my phone into a shiny paperweight or small cocaine tray. Anywhere I have read up on this, when it says download/install _______, I cannot determine whether that means download/install on my PC, or on my phone, bc it doesn't specifically say what goes where in every instance. To make matters more difficult, I do not have an internet connection other than on my phone. Anything that needs to go on my PC, I have to download it to my phone first, then transfer it over, then install it. I asked once for a step by step tutorial or a link to one, and I was given something that was just as confusing as what I have already found. These tutorials seem to be written for ppl who know a lot by ppl who know a lot. I am not one of those ppl. I am a green noob, still wet behind the ears. I apologize in advance for not knowing, but I am just not at the level where I can guess which things go where and If I temporarily render my phone unusable, I won't be able to easily go online to find the fix, nor will I be able to download anything else, if needed. Would greatly help me if I had a list of ingredients needed before I begin, and a sequence, much like a recipe for a cake. Again, I apologize for not knowing, and I'm sure all of you reading this were, at one point, uneducated on the matter. Thank you for any advice and/or reading my TL/DR post.

TWRP is a custom recovery, and what that is, is explained in "that" thread I linked you to: https://forum.xda-developers.com/showthread.php?t=2744194
Think of TWRP as a kind of small installer program and backup/recovery tool. You need it to flash custom ROMs, and you can also use it to backup the current ROM. It's not used within the Android OS, but rather you can boot into it separately. Which is obviously handy, if for whatever reason you can't boot to Android OS, and need to "recover" (restore the OS).
I need to have root access or a previous version of TWRP already installed, or I need to install the SDK tools package, and from that, only install fastboot and adb. Then after that I need to already have some type of drivers on my PC for that to be useful.
Don't go by the install instructions on the TWRP website, they are not device specific (to the M8) and may misguide you (every Android device has it's own nuances).
To install TWRP, you need to unlock the bootloader. The bootloader is "locked" by default, which by definition means you cannot install a custom recovery. The following is a good step-by-step guide to unlock the bootloader and install custom recovery. Note, that you do not need to root, in order to install TWRP, or flash a custom ROM. So stop before you get to the step of root (flash SuperSU). Also, the version of TWRP you install should be current (3.1) or alternately 2.8.7 (which is a known "old reliable) version).

No, you actually can't. Your fear of bricking the phone (permanent damage) is unfounded. As with s-on, this phone is nearly impossible to brick. The phone is fully recoverable even if you screw up; since for what you describe, you are only touching a limited number of partitions (system which is the OS, and recovery). As long as you don't mess with "critical" partitions like hboot and radio, you can't actually brick this phone. And those partitions are actually protected, and you can't modify them even if you wanted, unless you s-off. So all the more reason to stay s-on, as I described in the other thread you posted in here: https://forum.xda-developers.com/showpost.php?p=74107487&postcount=100
To make matters more difficult, I do not have an internet connection other than on my phone. Anything that needs to go on my PC, I have to download it to my phone first, then transfer it over, then install it.

That part is difficult. While possible, doing what you describe is somewhat risky with no other device for internet. At some point, it's almost inevitable for anyone tinkering these phones, that something will go wrong. Either you forget a step, or you can't boot for no mistake of your own, at all. Even having done this stuff for years, it still happens to be, once in a while. It just happens. So without a way to ask for help, or download files, you can get stuck in a bad jam. You'll need to have some backup plan, even if it's a friend or family, letting you use their computer as a last resort.

Stick with it. Keep reading up, and trying to learn the basic terms, concepts, tools, and methods. I know it seems overwhelming, but it will all start to make sense. You really can't (and shouldn't) try doing these things, until you have some basic understanding. You wouldn't ask someone to tell you how to tear the engine out of a car, without knowing how any tools work, or what any of the parts of the car are called.
I would also suggest you refer to my (AT&T M8) index thread. It has a lot of links and basic info, you may find useful: https://forum.xda-developers.com/showthread.php?t=2751432
